The engine of the new Murciélago LP640 has undergone outstanding and radical modification. The increased bore and longer stroke have boosted the displacement of the classic 60° V-engine from 6.2 litres to 6.5 litres (6,496 cm3). Thus the already extraordinary 580 hp engine power has now been elevated to an impressive peak of 640 PS (471 kW) at 8,000 min-1. The 12-cylinder engine reaches a maximum torque of 660 Nm at 6,000 min-1. Naturally, the Lamborghini Murciélago LP640 complies with every European and North American law governing exhaust fumes.
This evolutionary leap forward has been possible thanks to a coherent review of every engine component: the cylinder head and the entire intake system (based on the tried and tested Lamborghini variable geometry system), have been completely reworked. The crankshaft, camshafts and exhaust system have also undergone innovation.
The increase in power naturally determines an increase in performance. The excellent performance of the Murciélago LP640 means it can now accelerate from 0 to 100 km/h (62 mph) in 3.4 seconds (0.4 seconds faster than the previous model).
The electronics have also been updated. The modified engine control units improve engine performance and driveability thanks to closed loop control. Every engine and vehicle parameter is managed and controlled by three master control units and a satellite control unit. The master control units consist of two Lamborghini LIE engine control units, a Lamborghini GFA (Auxiliary Function Management) control unit and a Lamborghini PMC (Power Motor Control) satellite control unit. The control units are interconnected by a CAN Bus line.
The body of the Murciélago LP640 with its characteristic scissor doors is created from the prized union of sheet steel and honeycombed carbon fibre, glued and riveted together.
Driving, handling and stability at high speed are enhanced by new springs and stabilisers, as well as by a redesigned electronically controlled damper. The antidive and anti-squat features on the axles, which efficiently prevent so-called ‘brake diving’ and ‘squatting’, have not been changed. The two springs on every rear wheel, the single spring on every front wheel and the damper are placed coaxially.
A super sports car such as the Lamborghini Murciélago LP640 ensures high safety levels. The dual hydraulic circuit brake system equipped with a vacuum brake booster ensures considerable deceleration values. The self-ventilating front and rear brake disks measure 380 mm x 34 mm and 355 mm x 32 mm respectively. The control circuit of the four-channel anti-blocking system (ABS) with electronic brake control (DRP) and traction control (TCS) features a new characteristic curve. The
system consists in an electro-hydraulic control unit and four speed sensors. source
